Be it known that EDWIN M. Rif-icon, a citizen of the United, States, residingV at Tulsa, in the county of Tulsa and State of klahoma,A has invented certainV new and useful lmjnovementsin Road or Street la.7n inglofwhich the .following is a. specification.

.This invention relates to improvements in the constructionof road or street paving, and contemplates 'the provision of a metallic framework or a series-.of metal stay members: for locking the adjacent layers of paw inginateriallas set forth in my prior application, Serial No.`6'92,262,'liled February 12, 192e. j

.Inthe .present application,".the` main ob* ject of the invention isi to provide a constructionwhich willi function as heretofore indicated and which, at the same time will be cheap. to manufacture, and convenient to apply in use.

More specifically, the present invention provides a multiple series of stay members or metallic loops which may or may not be utilized with reinforcing bars, and these loops are arranged in predetermined spaced relation and in such a manner as to form a binding medium between a layer of concrete and a layer of asphalt.

Reference will be had to the accompanying drawings forming a part of the specification and wherein like characters of reference designate corresponding parts throughout the several views, in which Fig. 1 is a transverse sectional view through a paved street and showing one form of the invention in use in connection with reinforcing bars; Fig. 2 is an enlarged perspective of the reinforcing element;

Figs. 3, 4 and 5 show perspective views of modified forms of loops applied in connection with longitudinal and transverse reinforcing bars; and

l Fig. 6 is a fragmentary section through an asphalt coated roadway showing a modified form of loop in use without the reinforcing bars.

Referring now to Fig. 1,;the curbings 1 and 2are shown with adjacent gutter sections 3 and ll, and between these gutter sections is the conventional form of roadway or street paving including the concrete base and the asphalt coating 6. Longitudinal reinforcing bars 7 are shown embedded in the concrete base and above these longitudinal bars 7 are the `transverse'- bars 8. The size and constructionof these reinforcing bars 7 and 8 isa matter of discretion, and can only `be determined the nature of the roadway under construction.

The binding` loops shown in that form of the invention illustrated in Figs. 1 and 2, each consist of a section ofiwire the intermediate portion of `which is bent to form the open body portion 9 andthe Contact ing portions 10. The terminals are bentat right an 3les` to @the contacting portion 10 and. form hook membersllluwhich are designed to engage beneath the longitudinal reinforcing bars 7. The lfunction-aot' these hook members witlrwhich `each loopis `provided is to retain these partsfin their `proper position and to facilitate the n'ianipulation and application.

ln .thatform of the'.invention-shownin Fig. 8, the reinforcing bars 12 and 14.-, which correspond tothe bars 7 and 8 in Figs. 1 and 2, are used in connection with a similar arrangement of loop members; however, these loop members are of different construction in that the body portion 15 is defined by the bent terminal 1G of one of the Shanks, the opposite shank l? being elongated. It will be observed that the elongated shank 17 is arranged adjacent and seats in the pocket formed by the crossing of the reinforcing bars 12 and 1li, and the projecting portion 16 extends under one of these bars and forms a hook for retaining the construction in position.

In Fig. Ll, the reinforcing bars are indicated by reference characters 18 and 19, and the binding loop is similar to that form shown in Fig?) with the exception that one of the shanks of the loop vis coiled about one of the reinforcing bars as shown at 20 and is thereby held in fixed relation therewith.

Referring now to Fig. 5, the reinforcing bars 21 and 22 are of the usual form, but the loops are fixed at both extremities. It will be noted that the legs of this loop are spacer and extend parallel and their extremities 23 are coiled around the bar 22 on opposite sides of the bar 21. .This arrangement not only provides for the permanent placing of the loop, but also limits the movement of the bar 21 with relation to the bar 22. ln many instances, it may prove advisable to weld the loop to the bars.

lVhen it is not considered essential to use the reinforcing bars, same can be omitted from the concrete base and that form of loop shown in Fig. 6 may be utilized. This form of loop is very similar to the first three forms heretofore described, except that no hook or coil is provided for locking saine to the reinforcing bars. By reference to this figure, this loop Will be seen to comprise a single piece of Wire bent to form a loop portion 24 and having one shank 25 extending Well belov.'v the other. ln this ligure, the loop is shown embedded in the concrete base 2G, and the upper part of the loop 24 extends into the asphalt coating 27. Obviously, the from shoivn in Fig. 5 may be used in the saine manner as the form in Fig. 6.

An examination of the various arrangements illustrated in the accompanying draivings and described in the foregoing specification Will disclose to one skilled in the art the similarity of the idea involved. lt Will also be apparent that the different construen tions and arrangements may be desirable under various conditions and circumstances.

Various modifications in both the con struction of the loop and in the arrangement of the loop in thel roadway construction7 either with or Without the reinforcing bars, may be made Without departing from the spirit of the invention.

lVhat I claim as ne7 and useful, and desire to secure by Letters Patent is 1. A paving construction including a layer of base material, a plurality of longitudinal and transverse reinforcing bars, a plurality of loop members arranged at the points of intersection of said longitudinal and transverse reinforcing bars, the ends of said loop members being hooked for engagement With the under surface of the adjacent portions of reinforcing bars and a coating layer on said base material.

2. Roadway construction comprising a layer of base material, a plurality of reinforcing intersecting members, embedded in said base material, a plurality of loop members embedded in said base material and eX- tending above the surface thereof, said loop members having shank portions projecting laterally for engagement with the reinforcing bars adjacent their points of intersection, and a coating layer on said base layer.

3. A roadway construction comprising a base, a layer of surface material, and a binding member therefor, said member being formed with a loop embedded in the surface layer, and With a shank and a loop closing portion embedded in the base.

ln testimony whereof I affix my signature.
